The themometer showed this when i pulled it out if the mouth.I panicked! Downed some paracetamol and many other stuff and went ahead with the pole show tonight. I did it because of a nice colleague. He had offered to tell the client to remove my show and refund the money to them. He said it's not worth it if I injure myself. I told him "no" I would do the show for him, and I did. Even receive accolades from the client.
Actually it felt quite good after sweating it out :)
